This week, the spectre of more Tube strikes still looms as the RMT, TSSA and Unite members plan to walkout for 24 hours on 25 and 27 August. Sources from both London Underground (LU) and the unions have told IBTimes UK that talks have been "productive" and "constructive", but the industrial action over pay and conditions relating to the new Night Tube service is still on.

RMT representatives held a mass meeting to discuss the issue. Negotiators reported that they had made some progress but the two walkouts were still on the cards. Meanwhile, the union has attacked Aslef for not calling strike action.

IBTimes UK reported that an RMT newsletter bashed the Tube drivers' union for not sticking together and alleged Aslef top brass had "reneged on the agreement to strike and called off action without discussing it with other unions".

But Mick Whelan, the general secretary of Aslef, told IBTimes UK: "We are still in dispute with LU, but we are at talks today and, dependent on the outcome, will decide what action we may or may not take."

Talks are planned among all of the Tube unions and Underground bosses at mitigation service Acas on 20 and 21 August. The Night Tube target start date of 12 September is subsequently under threat. But LU has said it is still "operationally ready".

Blunkett blasts Corbyn

David Blunkett has become the latest Labour grandee to attack Jeremy Corbyn after the likes of David Miliband, Tony Blair and Gordon Brown have attempted to stop the socialist's leadership surge. Blunkett, a former home secretary, said he embraced radicalism at the top of Labour but wanted his party to win the 2020 general election.

"I want someone who can be radical, can have a very clear vision of where Britain will be in five years' time and above all can actually do something about winning," he told BBC Radio 4's Today programme.

However, the intervention could risk boosting Corbyn's campaign. A revised YouGov poll put him 37 points ahead of Andy Burnham and therefore set to be announced as Ed Miliband's successor on 12 September at a special conference.

#PringleDave

And finally, some important public interest news for you. A video of David Cameron eating Pringles has gone viral. The crisp-munching prime minister was filmed feasting on the paprika-flavoured snack as he travelled on an EasyJet flight from Portugal back to the UK after a family holiday.

The Old Etonian was apparently videoed by Ashleigh, a 16-year-old who was travelling alongside her boyfriend on the same flight as Cameron. The video went viral after Ashleigh posted it to Twitter. With the House of Commons in recess until 7 September, Westminster watchers quickly devoured the news.

A spokesperson from Pringles, which is owned by Kellogg's, welcomed the news. They told IBTimes UK: "Today we've had ringing endorsements from One Direction's Louis Tomlinson and Prime Minister David Cameron. From pop stars to politicians, no one can resist a good Pringle when they're peckish."
